Safety notice
General safety instructions
WARNING
: All internal components and component boards, with the exception
of the galvanically separated input and output terminals are connected to high
voltage when the AC drive is connected to the mains. It is extremely dangerous
to touch these live parts. Touch may cause severe injury or death.
NOTE!
The I/O terminals are separated from the high potential of the mains, but the relay outputs and
other I/O terminals may carry high voltages even if the AC drive is not connected to the mains.
NOTE!
Do not perform any high pot tests (megger) on the filters. The VACON
®
RFI filters are intended for
use in grounded supplies only. For ungrounded (IT) supplies, contact our representative or us.
WARNING
: Installation and service work only by qualified electricians.
WARNING
: No work on an operating unit. Contact with the electrical parts may be
fatal, even after disconnection from the power network.
WARNING
: To avoid electrical shock hazard:
- Before servicing the unit, wait at least the voltage discharge time stated in the user
guide for the corresponding AC drive.
- Dangerouse voltage may be on the unit even when the motor is not rotating.
WARNING
: Never attempt to repair a defective unit.
WARNING
: The unit surface temperature rises during operation. Avoid any contact.
